FOUNTAIN SPRAY-NOZZLE.

Specification of Letters Patent.

Patented Jan. 13, 1914.

To all whom it may concern:

Be it known that I, JAcoB Loosen, a subject of the Emperor of Germany,residing at Oakland, in the county of Alameda and State of California,have invented new and useful Improvements in Fountain Spray- Nozzles, ofwhich the following is a specification.

This invention relates to fountain spray nozzles, and particularly to aportable nonrotary nozzle fountain.

The object of the present invention is to provide a substantial, cheap,portable fountain, having detachable, interchangeable, non-rotarynozzles which are so perforated as to effectually shower water over anarea of peculiar or given shape.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which Figure 1 is aperspective View of the improved fountain partly in section. Figs. 2, 3,and 4 show types of the improved spray nozzle, interchangeable on thefountain for showering areas of different form.

In its illustrated embodiment my invention consists of a peculiarlyshaped sled or skid, consisting of two parallelly disposed, verticallyarranged, spaced loop-shaped runners 22, preferably made of fiat stock;the rounded ends of the runners forming noses for the ready clearance ofgrass, bushes, or other similar obstacles in the path of the sled whendrawn about. The upper portions of the loops or runners 2 are rigidlyconnected by a transverse tie or bearing member 3, which is centrallythreaded as at 4.- for the reception of the lower end of the tubularstandard or pipe section 5. The bearing plate 3 is preferably made ofthin material so that the lower end of the standard 5 will projectsufliciently to provide ample bearing for an elbow 6, externallythreaded at- 7 for the reception of a hose and coupling, indicated indotted lines. The upper end of the standard 5 is threaded as at 8 forthe reception of a reducer or other connection 9, internally threaded asat 10.

One of the important features of my present invention is to provide aspray fountain which can be readily moved from place to place, and toprovide in the fountain structure, spray-nozzles of which I show aplurahty of types; each being designed to efiectually irrigate areas oflawns or gardens of different contour or plan. In Fig. 1 I have shownone of the spray-nozzles 11 as being of substantially hemisphericalform, with a substantially fiat diametric base or .bottom, to which isappropriately secured a threaded nlpple 12, adjustable in the reducer orpermanent connection 9 of the fountain standard.

That type of spray-nozzle illustrated in Flg. 1 is shown as beingprovided with a number of substantially spirally arranged rows 13 ofapertures 14, which I particularly prefer to form of graduallydecreasing size, beginning largest at the base of each of the rows 13,and diminishing in size toward the upper portion or top of thehemisphere. This peculiar arrangement and area of the holes is of doublefunction. First, by providing the lower portion of the hemisphericalnozzle 11 with the largest apertures 14 then the water under pressure inthe nozzle will send the lowermost sprays issuing from the apertures thegreatest distance from the fountain; the gradually decreasing size ofthe holes of the spray proportionately decreasing the distance to WhlChthe spray is sent from the nozzle; and, secondly, arranglng theapertures in spiral rows, which results in avoiding large blank areas ina straight line from the base to the top of the spray-nozzle, the effectof which is to insure the shower or spray over the entire surface of agiven area to be irrigated since the spiral arrangement of the aperturesproduces a rain-like uniform series of sprays which fall in verticalplanes, each spray reaching a given part of the area to be showered, andavoiding the possibility of leaving large unshowered areas, such aswould be the case if the apertures 14 were arranged in parallel, radialor concentric lines in the nozzle.

For the purpose of ornamenting, and also for reinforcing and locking thestandard with its associated parts upon the sled or plate 3, a suitablejam or locking device 15 is here indicated as a polished or platedsleeve introduced above the plate 3 and below the connection 9, whichlatter, when screwed down tightly upon the jam member 15 holds theseveral parts in rigid relation.

In Fig. 2 I have shown a perspective view of a semi-cylindrical nozzle11, which is particularly useful when interchanged with the nozzle 11 onthe fountain for irrigating oblong areas; the apertures in the nozzle 11being arranged in helical lines, or in staggered relation.

In Fig. 3 I have shown an interchangeable spray-nozzle 11 ofsemicylindrical form, in which the apertures are limited to an area ofsubstantially rectangular boundaries in lan over the surface 0 thenozzle, and w ich nozzle when adjusted upon the fountain is particularlyuseful when irrigating rectangular areas. I

It is understood that I may design and provide interchangeable nozzlesof the desired contour in which I arrange the apertures 14 in spiral orhelical rows for the purpose of equally distributing the jets or spraysof water over the area to be irrigated.

By my peculiar construction of spray fountain I am enabled toefiectually irrigate areas of certain outlines and avoid the waste ofwater which commonly occurs while lawns and gardens are being sprayedwith hand hose or with portable fountains having rotary spray devices,and which occurs when any fountain is used which is not particularlydesigned to limit its showering sprays to within certain givenboundaries,

which, I effectually accomplish by my fountain by the simpleinterchanging of one or the other appropriately designed spraynozzles.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is

A portable s rinkler of the class described comprising in ependent,endless, flat, oval, parallel runners having a connectin tie boltedacross the center of the upper si es of the runners, a vertical tubescrewed to the center of the tie and a connecting elbow below a convexperforated spray head with a coupling member attached to the top of thetube, and a sleeve surrounding the tube having its lower end abuttingupon the tie plate and its upper end abutting the coupling member andcompressed thereby upon the tieb plate to form a rigid support for thetu e.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
